# Oracle Siebel CRM Marketing: privileged local user can alter some data

Oracle Siebel CRM's Marketing component has a flaw that lets a highly privileged user with logon to the infrastructure read, change or delete a subset of accessible data and cause a partial denial of service. The attack is difficult to carry out and requires high privileges, so it is a low-risk local issue rather than an internet-facing takeover.
